[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] When dust accumulates on the heat exchanger of the outdoor unit of a parking air conditioner, it can be assumed that the intake resistance increases when the fan speed is constant. According to the intake resistance formula: R=λ / d*(u^2γ / 2), where R is the resistance (Pa), λ is the resistance coefficient (usually a constant), u is the air velocity (m / s), and γ is the density of air (usually a constant), it can be seen that when the intake resistance increases, i.e., when dust accumulates or even clogs the condenser of the outdoor unit of the parking air conditioner, the corresponding outlet air velocity u decreases. Correspondingly, due to the increased air resistance, the load on the fan to reach the target speed increases, and the battery power consumption also increases accordingly.

[0027] This invention provides a self-cleaning control method for parking air conditioners.

[0028] Figure 1 This is a schematic diagram of an embodiment of the self-cleaning control method for parking air conditioners provided by the present invention.

[0029] like Figure 1 As shown, according to an embodiment of the present invention, the self-cleaning control method of the parking air conditioner includes at least steps S110, S120, S130 and S140.

[0030] Step S110: Accumulate the running time of the outdoor fan of the parking air conditioner to obtain the cumulative running time of the outdoor fan.

[0031] Step S120: When the cumulative running time of the outdoor fan of the parking air conditioner reaches the first preset running time, control the other components of the parking air conditioner (such as the compressor and throttling element) to stop working, and control the outdoor fan to run at a preset speed R1 for a first preset time T1.

[0032] Step S130: Obtain the battery power consumption Q of the vehicle where the parking air conditioner is located within the first preset time T1. 自清洁控制 and the air outlet speed V of the parking air conditioner 自清洁控制 .

[0033] The first preset running time T 自清洁控制1 This refers to the preset cumulative operating time of the outdoor fan when determining whether self-cleaning is needed, i.e., when the cumulative operating time of the parking air conditioner's outdoor fan reaches the first preset operating time T. 自清洁控制1 At this time, a self-cleaning judgment is made as to whether self-cleaning is required. When the cumulative running time of the parking air conditioner's outdoor fan reaches the first preset running time T... 自清洁控制1 Then, all electrical components of the parking air conditioner are stopped, and the external fan runs at a preset speed R1 for a first preset time T1, while the battery power consumption Q during the current time T1 is recorded. 自清洁控制 And the current outlet wind speed V 自清洁控制The cumulative operating time begins from the first operation of the external fan. After the self-cleaning control is executed, the cumulative operating time is reset to zero and the timing restarts.

[0034] Specifically, the battery power consumption Q within the current first preset time T1 is recorded by the battery power consumption monitoring module. 自清洁控制 The current outlet air velocity V is recorded by the outlet air velocity monitoring module. 自清洁控制 . Figure 2 This is a schematic diagram of the outdoor unit of a parking air conditioner according to the present invention. Figure 2 As shown, the parking air conditioner includes an outdoor unit 1 and an air outlet speed monitoring module 2. The air outlet speed monitoring module 2 can be installed on the air duct of the parking air conditioner and can monitor the real-time air outlet speed. Figure 3 This is a schematic diagram illustrating the components of the parking air conditioning controller according to the present invention. Figure 3 The control module for implementing self-cleaning control shown consists of controller 3, battery power consumption monitoring module 4, external fan speed monitoring module 5, timer module 6, and the aforementioned... Figure 2 It consists of an air outlet speed monitoring module 2; a battery power consumption monitoring module 4 for monitoring battery power consumption; an external fan speed monitoring module 5 for monitoring external fan speed; and a timer module 6 for timing the cumulative running time of the external fan.

[0035] Step S140: Determine the battery power consumption Q of the vehicle where the parking air conditioner is located within the first preset time T1. 自清洁控制 Whether it is greater than the first target threshold and the air outlet speed V of the parking air conditioner 自清洁控制 Is it less than the second target threshold?

[0036] Step S150, if it is determined that the battery power consumption Q 自清洁控制 If the airflow is greater than the first target threshold and the air outlet speed is less than the second target threshold, then the parking air conditioner is controlled to perform self-cleaning.

[0037] Specifically, the first target threshold is a preset battery power consumption threshold, and the second target threshold is a preset air outlet speed threshold. If the battery power consumption exceeds the first target threshold or the air outlet speed is less than the second target threshold, it indicates that the outdoor unit heat exchanger has accumulated a lot of dust, meeting the conditions for self-cleaning. That is, when it is determined that the battery power consumption Q of the vehicle where the parking air conditioner is located within the first preset time T1 is met... 自清洁控制 The airflow velocity V of the air conditioner is greater than the first target threshold. 自清洁控制 If the value is less than the second target threshold, it means that the conditions for performing self-cleaning have been met, and the parking air conditioner is then controlled to perform self-cleaning.

[0038] Figure 4 This is a schematic diagram of another embodiment of the self-cleaning control method for parking air conditioners provided by the present invention.

[0039] like Figure 4 As shown, according to another embodiment of the present invention, the self-cleaning control method of the parking air conditioner further includes steps S102, S104 and S106.

[0040] Step S102: When the parking air conditioner is started for the first time, control the parking air conditioner to not work except for the external fan, and control the external fan to run at a preset speed for a first preset time T1.

[0041] Step S104: Record the first battery power consumption Q1 of the vehicle where the parking air conditioner is located and the first air outlet speed V1 of the parking air conditioner within the first preset time T1.

[0042] Step S106: Determine the first target threshold based on the first battery power consumption Q1, and determine the second target threshold based on the first air outlet speed V1.

[0043] Specifically, when the parking air conditioner is used for the first time, all electrical components except the outdoor fan are not started. Only the outdoor fan is controlled to run at a constant preset speed until a preset time T1. The truck battery power consumption monitoring module records the first battery power consumption Q1 within the current time T1, the outdoor fan speed monitoring module records the first speed R1 of the current outdoor fan, and the air outlet speed monitoring module records the current air outlet speed V1.

[0044] The first target threshold is equal to the product of the first battery power consumption Q1 and the preset power consumption correction constant α; that is, the first target threshold for implementing self-cleaning control is α*Q1, where α>1. The preset power consumption correction constant α can be used as a set value in the control program. Since the battery power consumption will increase after the condenser becomes dirty and clogged, a judgment value is needed to determine the actual battery power consumption level at which self-cleaning needs to be performed. That is, the first target threshold for determining whether self-cleaning needs to be performed is the product of the correction constant α (α>1) and the power consumption during the first preset time T1 of the initial start-up operation.

[0045] The second target threshold is equal to the product of the first outlet air velocity V1 and the preset air velocity correction constant. That is, the second target threshold for self-cleaning control is β*V1, where 0 < β < 1. The preset air velocity correction constant β can be used as a setting value in the control program. Since the outlet air velocity will decrease after the condenser becomes clogged, a judgment value is needed to determine the actual outlet air velocity at which self-cleaning needs to be performed. This is determined by multiplying the correction constant β (0 < β < 1) and the outlet air velocity at the first preset time T1 of the initial startup.

[0046] Furthermore, if it is determined that the battery power consumption is less than or equal to the first target threshold or the air outlet speed is greater than or equal to the second target threshold, then the cumulative running time of the external fan is reset to zero, and the running time of the external fan of the parking air conditioner is re-accumulated for re-judgment. That is, the parking air conditioner is controlled to stop working again except for the external fan, and the external fan is controlled to run at a preset speed for a first preset time. The battery power consumption of the vehicle where the parking air conditioner is located and the air outlet speed of the parking air conditioner are obtained again within the first preset time, and the first preset time is judged. The system checks whether the battery power consumption of the vehicle containing the parking air conditioner is greater than a first target threshold and whether the air outlet speed of the parking air conditioner is less than a second target threshold. If the battery power consumption is less than or equal to the first target threshold or the air outlet speed is greater than or equal to the second target threshold, the accumulated running time of the outdoor fan is reset to zero, and the running time of the outdoor fan of the parking air conditioner is re-accumulated. This process is repeated until the battery power consumption is greater than the first target threshold and the air outlet speed is less than the second target threshold, at which point the parking air conditioner is controlled to perform self-cleaning. Specifically, if both conditions cannot be met simultaneously, the timer module resets the accumulated running time of the outdoor fan to zero, and the timer re-accumulates the running time of the outdoor fan. The system continues to accumulate the running time of the outdoor fan until the accumulated running time of the outdoor fan reaches a second preset running time T. 自清洁控制2 Then, it is determined again whether the first and second target thresholds are met. Note that T... 自清洁控制1 >T 自清洁控制2 This ensures that the degree of dust accumulation is not too severe. The system continuously checks and determines whether the threshold conditions are met to initiate self-cleaning control. If the first and second target threshold conditions are met simultaneously, the parking air conditioner is controlled to perform self-cleaning. Otherwise, the cumulative running time of the external fan is reset to zero and the running time of the external fan is re-accumulated. After the cumulative running time of the external fan reaches the second preset running time, the system re-determines whether the first and second target threshold conditions are met, and so on.

[0047] To clearly illustrate the technical solution of the present invention, the execution flow of the self-cleaning control method for parking air conditioners provided by the present invention will be described below with a specific embodiment.

[0048] Figure 5 This is a schematic diagram of a specific embodiment of the self-cleaning control method for parking air conditioners provided by the present invention.

[0049] like Figure 5As shown, when the parking air conditioner is first turned on, all electrical components except the outdoor fan do not start. Only the outdoor fan runs at a constant preset speed until time T1. The battery power consumption monitoring module records the battery power consumption Q1 during the current time T1, the outdoor fan speed monitoring module records the current outdoor fan speed R1, and the air outlet speed monitoring module records the current air outlet speed V1. α*Q1 is used as the first target threshold for implementing self-cleaning control, and β*V1 is used as the second target threshold for implementing self-cleaning control. After time T1, all electrical components operate under normal control, and the timer module records the cumulative running time of the outdoor fan. When the cumulative running time of the outdoor fan reaches the first preset running time T... 自清洁控制1 Afterwards, all electrical components of the parking air conditioner stop working, and the outdoor fan runs at speed R1 until time T1. The battery power consumption monitoring module records the battery power consumption Q during the current time T1. 自清洁控制 The outlet air velocity monitoring module records the current outlet air velocity V. 自清洁控制 When Q is satisfied 自清洁控制 Greater than the first target threshold and V 自清洁控制 If the value is less than the second target threshold, the parking air conditioner will implement self-cleaning control. If both conditions cannot be met simultaneously, the timer module will reset the accumulated running time of the external fan to zero, and the timer will recalculate the accumulated running time of the external fan. When the accumulated running time of the external fan reaches the second preset running time T... 自清洁控制2 Then, a new judgment is made to determine whether the first and second target thresholds are met, until the conditions simultaneously meet the first and second target thresholds, at which point the parking air conditioner performs self-cleaning.

[0050] The present invention also provides a self-cleaning control device for a parking air conditioner.

[0051] Figure 6 This is a structural block diagram of an embodiment of the self-cleaning control device for a parking air conditioner provided by the present invention. Figure 6 As shown, the self-cleaning control device 100 includes: a timing unit 110, a control unit 120, an acquisition unit 130, and a judgment unit 140.

[0052] The timing unit 110 is used to accumulate the running time of the outdoor fan of the parking air conditioner to obtain the cumulative running time of the outdoor fan; the control unit 120 is used to control the other components of the parking air conditioner except the outdoor fan to stop working after the cumulative running time of the outdoor fan reaches a first preset running time, and to control the outdoor fan to run at a preset speed for a first preset time; the acquisition unit 130 is used to acquire the battery power consumption of the vehicle where the parking air conditioner is located and the air outlet speed of the parking air conditioner within the first preset time.

[0053] The timing unit 110 accumulates the operating time of the outdoor fan of the parking air conditioner using a timer to obtain the cumulative operating time of the outdoor fan. The first preset operating time T 自清洁控制1This refers to the preset cumulative operating time of the outdoor fan when determining whether self-cleaning is needed, i.e., when the cumulative operating time of the parking air conditioner's outdoor fan reaches the first preset operating time T. 自清洁控制1 At this time, a self-cleaning judgment is made as to whether self-cleaning is required. When the cumulative running time of the parking air conditioner's outdoor fan reaches the first preset running time T... 自清洁控制1 Then, the control unit 120 controls all electrical components of the parking air conditioner to stop working, and the external fan runs at a preset speed R1 for a first preset time T1, while recording the battery power consumption Q during the current time T1. 自清洁控制 And the current outlet wind speed V 自清洁控制 The cumulative operating time begins from the first operation of the external fan. After the self-cleaning control is executed, the cumulative operating time is reset to zero and the timing restarts.

[0054] Specifically, the battery power consumption Q within the current first preset time T1 is recorded by the battery power consumption monitoring module. 自清洁控制 The current outlet air velocity V is recorded by the outlet air velocity monitoring module. 自清洁控制 . Figure 2 This is a schematic diagram of the outdoor unit of a parking air conditioner according to the present invention. Figure 2 As shown, the parking air conditioner includes an outdoor unit 1 and an air outlet speed monitoring module 2. The air outlet speed monitoring module 2 can be installed on the air duct of the parking air conditioner and can monitor the real-time air outlet speed. Figure 3 This is a schematic diagram illustrating the components of the parking air conditioning controller according to the present invention. Figure 3 The control module for implementing self-cleaning control shown consists of controller 3, battery power consumption monitoring module 4, external fan speed monitoring module 5, timer module 6, and the aforementioned... Figure 2 It consists of an air outlet speed monitoring module 2; a battery power consumption monitoring module 4 for monitoring battery power consumption; an external fan speed monitoring module 5 for monitoring external fan speed; and a timer module 6 for timing the cumulative running time of the external fan.

[0055] The judgment unit 140 is used to determine whether the battery power consumption of the vehicle where the parking air conditioner is located is greater than a first target threshold and whether the air outlet speed of the parking air conditioner is less than a second target threshold within the first set time period; the control unit 120 is further used to: if the judgment unit 140 determines that the battery power consumption is greater than the first target threshold and the air outlet speed is less than the second target threshold, then control the parking air conditioner to perform self-cleaning control.

[0056] Specifically, the first target threshold is a preset battery power consumption threshold, and the second target threshold is a preset air outlet speed threshold. If the battery power consumption exceeds the first target threshold or the air outlet speed is less than the second target threshold, it indicates that the outdoor unit heat exchanger has accumulated a lot of dust, meeting the conditions for self-cleaning. That is, when the judgment unit 140 meets the condition that the battery power consumption Q of the vehicle where the parking air conditioner is located within the first preset time T1 is... 自清洁控制 The airflow velocity V of the air conditioner is greater than the first target threshold. 自清洁控制 If the value is less than the second target threshold, it means that the conditions for self-cleaning have been met, and the control unit 120 controls the parking air conditioner to perform self-cleaning.

[0057] Figure 7 This is a structural block diagram of another embodiment of the self-cleaning control device for parking air conditioners provided by the present invention. (See diagram below.) Figure 7 As shown, according to another embodiment of the present invention, the self-cleaning control device 100 further includes a recording unit 104 and a determining unit 106.

[0058] The control unit 120 is further configured to: control the parking air conditioner to not operate other components except the external fan when the parking air conditioner is first started, and control the external fan to run at a preset speed for a first preset time; the recording unit 104 is configured to record the first battery power consumption of the vehicle where the parking air conditioner is located and the first air outlet speed of the parking air conditioner during the first preset time; and the determining unit 106 is configured to determine the first target threshold based on the first battery power consumption and determine the second target threshold based on the first air outlet speed.

[0059] Specifically, when the parking air conditioner is used for the first time, all electrical components except the outdoor fan are not started. The control unit 120 only controls the outdoor fan to run at a constant preset speed until the preset time T1. The recording unit 104 records the first battery power consumption Q1 within the current time T1 through the battery power consumption monitoring module, records the first speed R1 of the current outdoor fan through the outdoor fan speed monitoring module, and records the current air outlet speed V1 through the air outlet speed monitoring module.

[0060] The first target threshold is equal to the product of the first battery power consumption Q1 and the preset power consumption correction constant α; that is, the first target threshold for implementing self-cleaning control is α*Q1, where α>1. The preset power consumption correction constant α can be used as a set value in the control program. Since the battery power consumption will increase after the condenser becomes dirty and clogged, a judgment value is needed to determine the actual battery power consumption level at which self-cleaning needs to be performed. That is, the first target threshold for determining whether self-cleaning needs to be performed is the product of the correction constant α (α>1) and the power consumption during the first preset time T1 of the initial start-up operation.

[0061] The second target threshold is equal to the product of the first outlet air velocity V1 and the preset air velocity correction constant. That is, the second target threshold for self-cleaning control is β*V1, where 0 < β < 1. The preset air velocity correction constant β can be used as a setting value in the control program. Since the outlet air velocity will decrease after the condenser becomes clogged, a judgment value is needed to determine the actual outlet air velocity at which self-cleaning needs to be performed. This is determined by multiplying the correction constant β (0 < β < 1) and the outlet air velocity at the first preset time T1 of the initial startup.

[0062] Furthermore, the timing unit 110 is also configured to: if the judgment unit 140 determines that the battery power consumption is less than or equal to the first target threshold or the air outlet speed is greater than or equal to the second target threshold, then reset the cumulative running time of the external fan to zero and re-accumulate the running time of the external fan of the parking air conditioner; the control unit is further configured to: when the cumulative running time of the external fan reaches the second preset running time, control the parking air conditioner to stop working again except for the external fan, and control the external fan to run at a preset speed for a first preset time; the acquisition unit is further configured to: acquire again the battery power consumption of the vehicle where the parking air conditioner is located and the air outlet speed of the parking air conditioner within the first preset time; the judgment unit is further configured to: determine again whether the battery power consumption is greater than the first target threshold and whether the air outlet speed of the parking air conditioner is less than the second target threshold; until the judgment unit determines that the battery power consumption is greater than the first target threshold and the air outlet speed is less than the second target threshold, the control unit controls the parking air conditioner to perform self-cleaning. Specifically, if both of the above conditions cannot be met simultaneously, the timing unit 110 resets the cumulative running time of the external fan to zero, the timer restarts the cumulative running time of the external fan, and the judgment is repeated until the external fan has accumulated a second preset running time T. 自清洁控制2 Then, it is determined again whether the first and second target thresholds are met. Note that T... 自清洁控制1 >T 自清洁控制2 This ensures that the degree of dust accumulation is not too severe. The process is cyclical until a threshold condition is met, triggering self-cleaning control. If both the first and second target thresholds are simultaneously met, the parking air conditioner is controlled to perform self-cleaning. Otherwise, the accumulated running time of the external fan is reset to zero, and the accumulated running time is recalculated. Once the accumulated running time of the external fan reaches the second preset running time, the first and second target thresholds are re-evaluated, and so on.
